Axle Dimensions

Hub Face and Spring Center Measurements on Standard Trailer Axle

There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle (when hubs are mounted on the beam).

The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.

If you are replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.

Dexter Axles

Dexter axles are made of high-strength steel and come with spindles and spring seats welded on. The spring seats are attached to the underside of the axle so that the leaf springs (sold separately) can mount beneath the axle. The result of this underslung design is a trailer that rides a bit lower for quick and easy loading and unloading.

Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer's tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.

Video Transcript for Dexter Axle Trailer Axles - Leaf Spring Suspension - T20BTR-EZ-7258 Review

Today we're going to review part number T20BTR-EZ-7258. This is the Dexter Idler Trailer Axle with the straigh easy lube spindles. This one is 72 inches long and has a 2200 pound weight capacity. Now when we do ship this to you, it would actually have the spindles covered, we use this heavy car gated tubing and then we tape in on around the spindle. Actually before we put the tubing on, we will actually have grease that we cover the machine surface with to help protect it and then the tubes put on and then taped around it. I left the one on that end just to show you how we do ship them. This one I've taken it off because I want to show you the spindle. Now this actual beam will act as part of your trailer suspension system. You can use it to replace an axle on your trailer or you can use it to fabricate a suspension to fit your application. It's made of a high strained steel construction. On the natural basically, there will be an actual bend right here in the center. As you can see there's space under there. Once your spring seats are on the bottom here, you'll see the bend goes up and the reason they do that, this will help create a 0 camber angle for even road to tread contact across the width of your trailer's tires. Basically having the center ride a bit higher and then the sides bent lower, this will allow the axle to give just enough to compensate for the low.

When you put your load on the trailer, it would push down and sort of even that out and give your tires even where all the way across the full tread. This will result in excellent straight line acceleration for steady and in line tracking Now the spring seats on the bottom would make this an underslung design axle. Basically with the spring seats welded to the underside, this is where your lease springs would mount to. With it being on the under side, it will give you a low ride height which will make it easier to load and unload your trailer. Now this is an idler axle beam which means there are no break mounting flinches welded on and it also has just a straight easy lube spindle, there's no drop to it. If you're not familiar with easy lube, basically what an easy lube spindle is, as you noticed there's a grease zerk fitting right here on the end of the spindle. What that allows you to do is pump grease in, goes through the inside and it'll come right off this hole here and that will fill the whole cavity of where your bearings are.

It saves you the hassle of having to on a standard axle which you'll have to do is unscrew, take your hub assembly off, take your bearings out, grease everything, put it, pack them and then put it back together. With the easy lube, put your hub assembly all up on there and then you just pump the grease in, so it makes it a lot simpler to lubricate. The spring seats here and the spindles are all welded on. Now a critical thing on axles is measuring the length of an axle beam. There are multiple ways to measure that, but there's 2 that are really the most accurate. The hub face to hub face and the spring center to spring center lengths are the most accurate. Hub face would be when you have your idler hubs slid on here correctly. You would measure basically from the base of 1 wheel stud on the hub to the other end, to the base of that wheel stud, on the opposite side. Once the hubs amount on that, that will give you the hub face to hub face measurement. The other one is the spring center.

This is the approximate width of your trailer. This is measured from the center of 1 spring seat of this side to the center of the spring seat on the other side. Basically, if you're replacing your trailer's axle, you should be able to figure out which type you need by determining the capacity of your trailer, the bolt pattern of your wheels, the break type and then these lengths. Basically what we're going to do by measure the spring seat, it's going to be center of that spring seat to the center of this one is going to be 58 inches on this axle. Again, the weight capacity if 2200 pounds. Now the hub face, I don't have the hubs on, so just to give you an estimate, hub face is going to be right at about 72 inches, hub face to hub face length on this axle. Now the tubing outer diameter right here is 1 3/4 inches. The spindle size is 1 1/16 diameter. And that should do it . Oh one last note I just want to let you know is that this white manufacturer's label that comes on an axle is recommended. Actually that is the back of the axle.

So with it mounted in this positioning, spring seats on the bottom, the bending up, this would mean the label or the sticker right here, this would be the rear of the trailer, this would be the front of the trailer. But that should do it on part number T20BTR-EZ-7258. This is the Dexter Idler Trailer Axle with the straight easy lube spindles.

As usual, I can get parts cheaper and faster from etrailer. I don't even look for local suppliers these days. Since I discovered your excellent website and in-stock supplies, I just order and poof it appears, magic! 334181

- T20BTR-EZ-7258

I inherited an aluminum trailer that ended up needing a complete overhaul and etrailer was the best resource I could have found. After researching extensively to find out what I needed and watching their videos on how to do it I ended up ordering an EZ-lube axle, galvanized hubs, springs and a hanger kit (in other words everything from the frame down). Everything shipped quickly and arrived in great shape. All the parts worked perfectly and I couldn't be happier! 316656

- T20BTR-EZ-7258

Bought this for my boat trailer. Great looking axle took all the measurements and it looked like it would fit. When I put my hubs on it they were about one inch short. So being short there are no threads to tighten the nut against the bearing. So now I need to order there hubs. This should be mentioned when you order the axle. Or give the hub over all length. 313851


The axel is working great with no problems.

- T20BTR-EZ-7258

Axle arrive in good condition. Went together like it should. Very happy with the product 281113

- T20BTR-EZ-7258

1 yr later, axle and bearing set is working well. I decided to replace the axle under my trailer rather than the whole trailer. I like the pre-bend in the tube for keeping tires balanced under load as well as the basic finish rather than bare steel. Purchase price made it even better after shopping around a bit. 250261


Doing well, as you know, the axle gets used only when the trailer does so it sits a lot. But I do enjoy that it has the pre bend to it so when loaded up it tracks true and the tire wear is even.

Scott - 01/30/2018


- T20BTR-EZ-7258

Shipped fast. Product seems strong. I do have a problem (not etrailer's fault), the axle I replaced didn't have a raised leave spring mount as this one does. That extra inch put my tires into the fenders (literally) :( will have to cut fenders off and probably end up getting another axle maybe one longer so I can have boat ride between fenders instead of over them. 217938

Check out the review video I attached for more info. We don't have a 3,500 lb axle that has those dimensions. 3,500 lbs is quite a bit of capacity for a 5 by 8 trailer, you might be able to get by with the 2k axle part # T20BTR-EZ-7258.

  • Hub Recommendation for Dexter Trailer Axle part # T20BTR-EZ-7258
  • The Dexter Trailer Idler Axle Beam with EZ-Lube Spindles # T20BTR-EZ-7258 that you referenced has a BTR spindle on it that takes a hub with an inner and outer bearing of L44649. This would not work with your hubs because they have inner bearing of L68149 and an outer bearing of L44649. To use the axle you referenced you would need to go with the Trailer Hub Assembly # 8-258-5UC1 instead. At 72 inches in length there are no axles we carry that would fit the hubs you have.

  • Axle Capacity of 1-1/2 Inch Square Axle.
  • The only way to know for sure the capacity of your axle is based on the information from the manufacturer when the axle is new. Typically, 1-1/2 inch square axels have a capacity somewhere between 1,000 - 2,000 pounds. Sometimes the spindle and hub can also help point us in the direction of finding axle capacity, but even then it is still an approximation since it is impossible to tell if they are the same size as what came on the axle. The bearing number your provided does not match...

  • 72 inch Long Trailer Axle Recommendation with 2,200 lb Capacity that can Fit 14 inch Wheels
  • The difference is the mounting flange on the hubs. Axles that have larger mounting flanges like the part # 20545I-EZ-72-15 can fit the larger wheels, whereas the # 20545I-EZ-72-10 has a small flange that doesn't match up to the bigger wheels. What you would want to do is go with the axle part # T20BTR-EZ-7258 that does not have hubs with it and then use the hubs # 8-258-50UC1-EZ that has the larger mounting flange on it and will give you the 2,200 lbs capacity you want in the correct size.

  • Do Hubs Come Pre-Installed on Dexter 2,200 Pound Trailer Axles
  • We do have a 72 inch, 2,200 pound trailer axle with hubs, # 20545I-EZ-72-10, but the hubs are not pre-installed. Everything is included (bearings, seals, races (the races already pressed in), grease caps, and lug nuts) just not pre-mounted. I have included a link to a video showing an example installation of this axle for you. This axle has hubs with a 5 on 4-1/2 bolt pattern. It is also available with a 4 on 4 bolt pattern # 20440I-EZ-72.

  • Recommended 72 Inch Axles And Brakes For Tandem Trailer
  • The 72 inch axles we offer have all got a weight capacity of 2,000 lbs. Also, none of the 72 inch axles have a brake mounting flange attached. You would need to have the components for a brake assembly installed on one of the axles. I recommend the Dexter Trailer Axle w/ Idler Hubs, part # 20545I-EZ-72-15, for the axle that you said you want free rolling. This has an EZ-Lube spindle with a 5 on 4-1/2 bolt pattern and has the bearings, races, seals and hubs included. This axle will work...

  • Straight Trailer Axles for a 2 Horse Trailer with 3,600 Pounds Gross Trailer Weight
  • With the trailer weighing 1,600 pounds and 2 horses at 1,000 pounds each that would total 3,600 pounds which is over the capacity of both a single 2,200 pound axle and a single 3,500 pound axle. But if you have 2 axles then using 2 of the 2,200 pound axles, # T20BTR-EZ-7258, will be more than enough capacity. I have linked a video review of this axle for you. If it is a single axle trailer then you will need to order one from a local trailer supply store with a high enough capacity for...

  • Key Dimensions for Selecting Replacement 2200-Lb Trailer Axle
  • The key dimensions to keep in mind as you select a replacement axle are the hub-face-to-hub-face dimension and the spring seat spacing. Axle # T20BTR-EZ-7258 is rated for 2200-lbs and has a 72-inch hub-face (HF) dimension and a 58-inch spring seat dimension as shown in the diagram I linked for you. Overall axle length will of course be a few inches greater than the HF spacing. The E-Z Lube spindle diameter is 1-1/16-inch. We have no axles with 72-1/2-inch hub face spacing.

  • What is the Capacity of the Axle in Dexter Trailer Axle Kit with Idler Hubs 20545I-EZ-72-15
  • For trailer axle # 20545I-EZ-72-15 the axle itself is rated for 2,200 pounds. The axle alone is # T20BTR-EZ-7258. The hubs that are included with # 20545I-EZ-72-15 are rated for 2,000 pound axles so since they are lower than the axle itself the rating for that whole system is 2,000 pounds. If you need a 2,200 pound set up you would use axle # T20BTR-EZ-7258 and 2 of hub # 8-258-50UC1-EZ.

  • Can Hubs from Old Axle Be Used With Dexter # T20BTR-EZ-7258 Replacement Trailer Axle
  • If your existing hub assemblies use the # L44649 inner and outer wheel bearing, hubs and races are still in good condition, you can reuse them. I'd recommend replacing the bearings and # L44610 races. I wouldn't recommend trying to bend the axle back into place. When the axle was bent, the structural integrity of the metal might have been compromised to an unknown degree. Be safe, replace the axle.

  • Which Hubs Fit Dexter Axle T20BTR-EZ-7258
  • The Dexter Trailer Idler Axle Beam with EZ-Lube Spindles # T20BTR-EZ-7258 that you referenced has a BTR spindle on it that takes a hub with an inner and outer bearing of L44649. For an idler hub you would want the part # 8-258-5UC1-EZ. Or if you want a brake drum you would want the part # 8-257-5UC3-EZ. Both of these hubs will fit the trailer axle and have the 5 on 4-1/2 inch bolt pattern you are looking for.

  • Replacement Trailer Spindle for L44643 Inner and Outer Bearings
  • A spindle that uses both inner and outer bearing L44643 makes it a BT8 spindle, # R104BT8. Please note that welding on new spindles is a precision job and should performed by a qualified welder with experience welding on spindles. The alternative is to replace the axle. Axles are measured from hub face to hub face and from spring seat center to spring seat center. For example, the picture I have included is for axle # T20BTR-EZ-7258.

  • Can Replacement Trailer Axle with Smaller Diameter be Used on a Boat Trailer
  • If the axle is bent up in the middle then that is normal. Trailer axles have a bow in them so that when weight is placed on the trailer it flattens out. That is part of what gives an axle its capacity. If there is not enough weight on the axle then the tires will remain toe in at the bottoms and you will get tread wear just on the outsides of the tread. If the axle is bent in some other way then replacing the axle is a good idea. The diameter difference means that you would likely have...
